The factor of safety is used in designing a machine component. Prior to selecting the correct factor of safety certain points must be taken into CONSIDERATION such as:

• The properties of the material used for the machine and the changes in its intrinsic properties over the time PERIOD of service.
• The accuracy and authenticity of test results to the actual machine parts.
• The applied load reliability.
• The limit of stresses (localized).
• The loss of property and life in case of failures.
• The limit of initial stresses at the time period of manufacture.
• The extent to which the assumptions can be simplified.

The factor of safety ALSO depends on NUMEROUS other considerations such as the material, the method of manufacturing , the VARIOUS types of stress, the part shapes etc.
